标签： javascript jquery json

尝试解析JSON时遇到错误：

 SyntaxError: Unexpected token u in JSON at position 0(…)   eFormsAtoZIndex.aspx:6558

有人能指出JSON结构或JS有什么问题，或者我如何调试其中的项目？

编辑（按照Jaromanda X＆CH和Buckingham的回复）：

$('#hdnAggregateAll').val(JSON.stringify(aggregateAll));
console.log(aggregateAll);          $('#hdnAggregatePersonal').val(JSON.stringify(aggregatePersonal));          $('#hdnAggregateBusiness').val(JSON.stringify(aggregateBusiness));          $('#hdnMinistryAggregate').val(JSON.stringify(ministryAggregate));
$('#hdnCAAggregate').val(JSON.stringify(caAggregate));
$('#hdnSTaxAggregate').val(JSON.stringify(sTaxAggregate));
$('#hdnBTaxAggregate').val(JSON.stringify(bTaxAggregate));
$('#hdnLETaxAggregate').val(JSON.stringify(leTaxAggregate));

在此之后，你试图得到json未定义的。 您可以在if-block中定义变量，但在这种情况下您应该添加一些验证。 

if (pubType=="eForm" || pubType=="PDF") {  
    var json = createJSONStructure(title, desc, index, type.toLowerCase(), formLink, documentLink, pubType, processId, ministry, ca, stax, btax, letax);
}
formItems.push(json);
